Application filed July 11, 1914. Serial No. 850,374.

To all whom it may concern:

Be it known that I, F WALTER GUIBERT, citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Circulators, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This inventionrelates to circulators for use in steam generating boilers.

It has for its object a circulator in the form of a saddle provided with legs. The saddle furnishes a maximum area of contact with a highly heated surface while the legs reach to the very bottom of the boiler and limit the amount of incoming Water, so as to give the contents of the saddle more time to become highly heated.

A further feature is the bell shaped mouth of the leg which is a preventive of sludgelifting.

In the drawings: Figure 1 is a vertical cross section. Fig. 2 is a vertical longitudinal section.

The boiler is here represented as a Scotch boiler but of course my invention can be used with other types of boilers. The boiler shell is designated a, the furnace chamber 6, and the combustion chamber Q.

Mounted upon the top of the furnace chamber are one or more saddles (Z of inverted U shape, closed at one end and at the lower extremities at each side. The other end has an opening 6, while legs f connect with the saddle at the bottom at each side. These legs lead down to the bottom of the boiler when they flare out to form bellshaped openings. These flaring openings cause an initial suction of a greater body of water than can be drawn up through the leg. This causes a certain amount of choking of the water so as to prevent the rapid circulation induced by the large heating area of the saddle from lifting the sludge, mud, etc., lying on the bottom of the boiler.

The legs carry the effective force of the suction to the very bottom of the boiler and by the constriction of the passage way of the water limit the amount of water that comes into the saddle in a given unit of tune. This allows a given quantity of water to remain alonger time in the zone of greatest heat, consequently greatly promotmg the strength of the circulation.

The top of the saddle slopes from the closed end toward the open end tending to deflect the discharging current in an upward direction. Both of the saddles discharge in the same directionso as not to cause collidmg currents.

I place upon the top of the combustion chamber another saddle g, which is the same 1n its general construction. This saddle may rest only upon the top or it may extend over the side some distance. It is provided with legs f the same as the saddles cl. This saddle g, is positioned directly the reverse of the saddles cZcZ, and it being nearly again as high in the boiler as they, it causes the currents to assume a spiral, the inner end and beginning of which is at the opening e-e and which is there traced (by reason of the upwardly inclined tops of the saddles cZcZ) curvilinearly upward and toward the combustion end, thence reversing in direction and flowing along the top of the water level of the boiler (by reason of the direction of discharge and the impetus created by the saddle g.) The currents there drop downward at the front of the boiler and mingle with the waters at the bottom to establish a uniformity of temperature at top and bottom.

I claim:

1. In combination with a boiler provided with a furnace chamber and a combustion chamber, a circulator system comprising one or more circulators adapted to rest on the furnace and arranged to discharge in one way alone, and a circulator located on the combustion chamber materially above the circulator or circulator-s on the furnace and arranged to discharge in directly opposite direction to the direction of discharge of the circulator or circulators .upon the furnace.

2. A circulator, having in combination, a saddle of inverted U shape, open upon the inside and at one end and closed at the other end and both of the lower extremities, and
